Application led February This invention relates to improvements in draw bars and the ob]ects of the invention vare tolprovide a durable device oi this character in which the sp ing-actuated retaining means for the draw bar is an essen` tial feature, being so constructed with few y parts as to .more satisfactorily perform the `functions required of it in automatically spring actuating` the 'draw bar.

Further objects are the provision of a device of this character ot' simplified and durable construction, more particularly adapted the coaches of a train and the tender.

Still furtl'ier objects are to provide a draw description that can be manu- Furtherrand essential objects are to` provide a spring-actuated recipi'ocaily.operable for locomostartingI or stopping cfa' train, all chuclr or starting performed 1in a smooth even manner.

With vthe foregoing and other hereinafter more fully referred to in view, the invention'consists essentially in the coinran e, bar member slidably mounted therein and ymeans formed on the'draw bar adapted to automatically engage when at restand on a plurality of spring 'actuating and tensioning' memberspivota'lly mounted in theframe, and means for lock- Referring now to the drawings, in which like characters `of reference indicate `corresponding parts in each figure.

'Figure 10 is a fragifnentar7 perspective view or the end ot one ot the channel plates, showing the slot and orifices therein.

Referring new moreparticularly to tlie drawings, in which a preferred example of my invention is shown in connection .vith a locomotive tender, 10 designates a iframe, of suitable material and any suitable form, provided `with a basell and ends 12 and lf3, the sides of the frame being open.

Extending,` longitudinally through the base l1 is a guideway 14 registering With and 16 in vthe ends. This guidcivay is provided with channel plates 717 'formed integral With the underside of the base 11 and protrudingbeyond one end,

4asat 18, to fit beneath a locomotive tender,

lthe `sides of the` protruding portion beingformed on the top With tia 19 and provided .with longitudinally extending` slots 2O substantially midway of their depth, the slots being designed to slidably engage with `guide members 21 adapted, at 22, to enn'age with the flanged edges 28 of said slots. These guide members 21 are thus interchangeable and at all times renewable when Worn out.

fithin the ,eguideway` 14 in the base and `the channel plates 17 is slidably mounted thefdraiv bar 24C designed to travelv backwards andtorwards therein. Adjacent one end ot the draw bar are supporting; guide llugs oi' pins 25 designed to engage With the .slots20 in the protruding' end 18 of the channel plates and also to engage with the .interchangeable guide members 21 slidably mounted therein. The other end of the draT bar 24is formed with a coupling meinber 27, of any yWell lknown construction, to connect With the coaches of a train While intermediate of its length the drawbar is provided With spaced lugs 28 and 29, the purpose of which is hereinafter more fully described.

From the foregoing it will beseen that the draw bar is slidably mounted in the base l1 on the frame 10 and that the openings 1.5 and lgin the ends 12 andl of the trame permit the'lunfs'28 and 29 onthe draw hat to move baclrivardl-v and forwardly through `said ends With the draw bar.

'Coinine' now to' the essential feature oit my invention. the means for imoartine the spring-actuated reciprocal movement to the raiv bar comprises pairs et finder bars 20 fili mounted, as at'32, in brackets 33, one of each pair on opposite sides of theguideivay la, and recessed at their inner ends, as at 34, to overlap, the outer ends being also slightly recessed, as at 35, to engage with a vertically extending slat 36 registering with a slat or plate 37 rigidly mounted on the ends 'i2 and 13 of the trame and having mounted thereon on pins or lugs 38 coil springs 39 andl a0, the other end oi said springs engaging With the slats or plates 3G carried by the 'linger bars 30 and 3l, thus imparting a spring actuating movement to each of the pivotally mounted finger bars.

intermediate of these finger bars on each sde ot the guideivay la are fiat plates or the like al and 42 formed with contact lugs at?) on each side, adapted to engage With the outer ends of the linger bars 30 and 3l io limit the travel thereof in one direction. Qn these plates are also mounted and sev sure-d thereto tensfon springs al connected to the plates and to the outer ends oi the individual linger bars, as at 35.

The pairs of linger bars 30 and 3l are designed. to engage with the lugs 28 and 29 on the dranT bar 24 and these linger bars, being pi'votally sioned, not only spring actuate the dranT bar in rest and in Operation but also impart a spring-actuated reciprocal movement thereto, as when the dravvr bar is connected up tension thereon Will be exerted in both directions, tension in one direction being counteracted by one pair of spring-actuated linger bars engaging With the block 28 and tension in the other direction being counter-acted by the other pair of springactuated nger bars engaging With the block or lug 29.

For supporting the draw bar in position and if necessary loelzing it Within the channel plates i7 and the guideivay la, I provide slots l5 in the sides of the channel member 1T vand also oriliees 46. lnto the slots 45 is adapted to tit a plate 4T bent, as at 48, at

ne end and provided with a slot i9 at the V- arotrudin end into which fits a locking D 3 7 lrey 50, While intermediate of its length is a riding plate l having formed on each side lugs 52 adapted to engage with pins 53 eX- tending through the oriiices i6 in the channel member.

'ilo remove the draw bar when unlocked the plate 47 is Withdrawn, permitting the coupling end ot' the draw bar to drop, The interchangeable guide members 2l are then Withdrawn and the draw bar moved outwardly until the supporting guide pins disengage with the slots 20. Under ordimounted and spring ten-` nary conditions it is usually unnecessary to do more than `drop the draw bar, leavingl the pin-carrying end pivotally supported in the slots 20.

F or protecting the reciprocating mechanism as above described, l provide a cover 54 for the casing frame and adapted to be suitably secured thereon.

As many changes could vbe made in the above construction and many apparently Widely dii'lerent embodiments of my invention, Within the scope of the claims, constructed Without departingl from the spirit or scope thereof, it is intended that all. matter contained in the accompanying specication and drawings shall be interpreted in an illustrative and not in a limiting sense;

What l claim as my invention is:

l. A draw bar having spaced lugs intermediate of its length, a frame, a guideivay in said frame, pairs of pivotally mounted spring-actuated levers arranged, one inember of each pair on each side of said guideivay adapted to overlap the other and to automatically engage with the lugs on the draw bar whereby a reciprocating spring actuating movement is imparted to the draiv bar.

2. fr dravv bar having spaced lugs thereon, levers pivotally mounted substantially midway et their length and one on the opposite side oit the draw bar from another and adapted to overlap each other across the bar and to engage with the lugs thereon, the other ends or' the levers being *spring actuated in opposite directions.

8. In device ot the character described and in combination with a slidably operable draw bar having spaced lugs thereon, a pair ot lever arms each pivotally mounted substantially midway of. their length one on each side of the draw bar, the ends oi the levers being adapted to overlap across the draw bar and to engage uith the lug thereon, springs at the opposite ends of said levers tending to actuate them in opposite directions whereby a reciprocal movement is imparted to the draw bar.

Ll. The combination, with a reciprocally mounted draw bar and a guidevvay adapted to support said bar, oi a clamping plate for the dra-W bar and having engaging means therein and designed to detachably engage with the guidetvay and to protrude therebeyond, a locking key adapted to engage With said plate and an auxiliary pin extending through the plate and the guideivay,

ln witness whereof I have hereunto'set my hand. Y

JAKOB GOHRING.
